FII PCE'LT'EQATION forming part of Letters Patent No. 344,981, dated July 6, 1886.

Application filed September 26, 1885. Serial No. 178,219; (No mo lel.)

To all whom it may concern:

Be it known that l, FREDERICK Orr, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Gigging- Machines, of which the following is a specification.

This invention has reference to improve ments in that class of machines by which a uniform nap is produced on woolen or cotton fabrics, as will be more fully described hereinafter, and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation of my improved gigging-machine with the carding-rolls removed. Fig. 2 is a side view of the driving mechanism of the carding-rolls, drawn on a.

larger scale, and also with the carding-rolls removed. Fig. 3 is avertical transverse section on line 00 :c, Fig. 2, showing portions of the cardingrolls.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a side frame of this improved gigging-machine, the two similar framesat opposite sides of the machine being connected by bolt-rods a. Each of these frames comprises the standards A, which are connected by cross-bars A and A and provided with brackets A", and a ring, A, supported by said standards and crossbars. A ring-shaped frame, F, is rigidly attached by means of lugs f and bolts f to the frames A. Centrally to the ring-sh aped frames F F is supported in bearings of the cross-bars A and rings A a driving-shaft, O, to the ends of which are keyed spider-frames having radial arms 0. The ends of the radial arms 0 are forked and provided with journal-bearings d d, for the journals of aseries of cardingrolls, B B, which are arranged in the form of a cylinder around the center shaft, 0. The journal-bearings d d are cushioned by spiral springs d d and forced toward U-shaped straps (l d", attached to the outer ends of the forked arms. To the journals of the cardingrolls B B are keyed, adjoining to the bearings d d, friction-pulleysf' which are covered with rubber and revolved in contact with the inner surfaces of the ring-frames F F.

The end straps, d (1 of the arms 0 C are detachable by being held in place by screws (2 or in any other manner, so that the journalbearings d d can be removed for repair in case they are worn out by use.

Rotary motion is imparted to the drivingshaft 0 by a belt and pulleys from a suitable power-shaft, whereby the carding-rolls are revolved by the driving-arms around the shaft and simultaneously rotated on their axes by the frictional contact of their pulleys f f with the ring-frames F. When heavy goods have to be napped, pinions have to be used in place of the friction-pulleys, which pinions mesh with an interior gearing of the ring-frames F. The carding-rolls B are covered with the usual cards or teasels employed in gigging-machines.

The standards A are provided at opposite ends with horizontal brackets A", on which are supported journal-bearings for a set of guide-rolls, g g, and a set of feed-rolls, g At the lower part of the frame A are arranged symmetrically to the axis of the frame, at one side, a pair of guide-rolls, g and at the other side a set of feed-rolls g" 9 Anumber of feed-rolls, D D, are supported in bearings of the rings A outside of the carding-rolls. Between each feed-roll and the carding-rolls and close to the latter is arranged a pair of stretching-rods, h h, which are supported in radial arms h h of the standards A A and adjusted thereon by slots h and clampingscrews h*, as shown in dotted lines in Fig. 1, so that the cloth to be napped can be adjusted accurately to the carding-rolls.

The cloth to be napped is passed over and between the left-hand set of guide-rolls, g g,

conducted over and between the left-hand set of rolls, 9 9 at the lower part of the frame A,

then over a fixed guiderod, i, to the stretching-rod h of the first feed-roll D, then over the latter and the second rod, h, to the stretching-rod h of the next feed-roll, and so on over all the feed-rolls and their stretching-rods to a rod, '5, arranged symmetrically to the rod 2', then over and between the lower right-hand pair of feed-rolls, g" and the pair of feedrolls g g to the winding-up roll, as indicated by arrows in Fig. 1.

The cloth to be mapped is slowly fed forward through the machine and over the carding-rolls by the feed-rolls D D, to which axially-rotating motion is imparted by an endless belt, m, that passes over pulleys m at one end of the shaftsof the feed-rolls D, and a tension-pulley, m", and by a second belt, a, which passes over a pulley, a, on the drivingshaft 0, and over a pulley, m, of one of the feed-rolls, and over pulleys n a on the shafts of the carding-rolls, as they act over and over again on the surface of the cloth.

The advantages of my improved giggingmachine are, first, simplicity of construction and comparatively small cost of the same; second, by accomplishing the carding operation by a series of individual rolls a uniform nap is imparted to the fabric, whichis gradually raised by the action of the cardingrolls, so that light cotton and woolen fabrics can be successfullyand uniformly napped; third, that owing to the frictional contact of the rubbercovered pulleys a smooth and regular motion is imparted to the carding-rolls, so that no injurious influence is exerted on the fabric.

Having-thus described myinvention, I claim as new and desire to secure by Letters Patent- 1. Ring-shaped frames, a shaft supported centrally therein, spider-frames on said shaft, carding-rolls journaled in the arms of said spider-frames and arranged in the form of a ring concentric with said ring-shaped frames, and means for imparting axial rotation to said rolls, in combination with rotary feed-rolls arranged around the outside of the ring of carding-rolls; means forlactuating said feed-rolls, and stretching-rods between the feed-rolls and carding-rolls, substantially as described.

2. Ring-shaped frames, a shaft supported centrally therein, spider-frames on said shaft, carding-rolls supported in the arms of said spider-frames and arranged in the form of a ring concentric with said ringshaped frames, and means for imparting axial rotation to said rolls, in combination with rotary feed-rolls arranged around the outside of i the ring of carding-r0lls, means for actuating said feedrolls, stretching-rods between the feed-rolls and the carding-rolls, and mechanism for adjusting said stretching-rods toward or from the centers of said feed-rolls, substantially as described.

3. Ring-shaped frames, a shaft supported centrally therein, spider-frames on said shaft, carding-rolls journaled in the arms of said spider-frames and arranged in the form of a ring concentric with said ring-shaped frames, and means for imparting axial rotation to said rolls, in combination with rotary feed'rolls arranged around the outside of the ring of carding-rolls, mechanism for actuating said feedrolls, stretching-rods between the feed-rolls and the carding-rolls,slotted arms,in the inner ends of which said stretching-rods are journaled, and screws passing through the slots therein and into said ring-frames, whereby saidframes are rendered longitudinally adjustable, substantially as described.

In testimony that I claim the foregoing as lnyinvention I have signed my name in presence of two subscribing witnesses.
